96% of NFL players studied post mortem had CTE, 79% of people who played football at any level tested as having it as well.
This is bad for football. Those kinds of percentages really shouldn’t be ignored, though some will point out that only people who agreed to have their brains studied after their death were part of the study, which would skew towards players who were already experiencing symptoms. That is true, but the numbers really seem to indicate that it’s not rare anyway you look at it.

Most prominent group is linemen (40 percent of those who tested positive) suggesting repeated, ‘minor’ head trauma is most dangerous threat to players. =======>>http://bit.ly/1Jff7bE
